7 To all whom it may concern:

. from. refuse Water,

Beit known that I, WILLIAM H. MoN 'r'r, citizen of the United States, and resident of New York city, in the county of New York and 'State of New York, have invented certain new and useful Improvements in Separators for-Oil and Gasolene, of which the following is a specification.

This invention has for its object to provide an improved means for the separation such as sewerage from buildings, and especially the draina e water from a garage or similar places wierethe water contains a large amount of oil ,and gasolene, that becomes collected in dangerous quantities in the sewers and results in frequent explosions.

A further object of the invention is to provide means whereby the heavier oils or grease that accumulate in the device can be properly removed through the employment of heat, so that part will be evaporated and driven oil" through an air vent, andthe remainder will be loosened to be removed by flushing and carried oil into the sewer.

In the accompanying drawings illustrating one embodiment of my invention, Figure 1 shows a tank with the several connections and the receptacle for the separated fluid; and Fig. 2 is an enlarged transverse section through the flushing pipe.

In the drawings 1 show a receptacle in the form of a drum 4 whose top is-provided with a conical extension 5 connecting with an out- ].et pipe 6 extending upward. The latter has a sight tube 7 of glass for observing the passage up from the tank. A p pe 8 e from the pipe 6 to a suitable receptacle 9, and is controlled by valve 10.

At the bottom of the drum 4 is a cone 11 connecting with an -outlet pipelQ. This pipe is provided with an upwardly extending leg 13 that is joined to a downwardly extending leg 14' by a portion 15 in whichis placed a valve 16. The part 15 is-level with the intermediate portion oflthe tank a, to act as a "fiuid retainer to maintain the water level of the tank at about the line 17. To vent this outlet-pipe 14 that connects with a pipe 18=leading to the sewen'lprovide an .air vent 19 in thepipe 15, thatjs controlled by valve 20,: that: is neiniallyolpened to ad m-it airanil break'the s hon: -t welLben-n: derstood that when this valveis closed the ads controlled by valve outlet will act as a siphon to flush the con: tentsof the tank.

An inlet pipe 21 leads into the tank at 22 and is controlled by valve 23. The pipe 21 leads from the floor of the ara' e, and also connects with the wash-Stan an bath room apparatus in'the building so as to receive all sewerage fluid. I also provide a pipe. 24 connecting with a water main and leading into the outlet pipe 12 at225. This water inlet is 6. Inside of the drum 4.- I member in the form of a cone 27 of perforated material whose upper end is secured to the lower portion of the cone 5, the lower convergingend of the screen 27 being, open place a screen and located in the lower portion of the drum 4, so that the fluid entering through the inlet pipe 21 can ,onlypass into the cone through the small openings, or through its lower end aperture.

- At the top of the screen 27, I arrange a suitable inlet device for hot water that will be discharged all around the circumference of the cone at this part. I show a coil of pipe 30 at the top of this cone having an inlet 31, the pipe being provided with small holes 32 in its. lower portion, whereby water flowing into the pipe will be directed against the inner surface of the cone tov flow down the same. The inlet 31 connects with a pipe 33 controlled by a alve 34:.

valve 23 and the outlet valve 16 are norhe sewerage water will flow into the tank through the pipe 21 and pass down through the same into the outlet "12 and up the leg 13, and this will cause the water to back up into the tank until. it reaches the highest portion 15 of the outlet pipe, which port on, as will be seen, is level-with the intermedlate portion of the to flo-w, the oil-andvgasolene, andall floatable fluid or. other material will rise to th top of the water in the tank a, to the line and accumulate above the same, and it will be seen that this level is above the bottom of the screen 2'}. Therefore as the fluid news into the the oil and gasqleneris:

mg at onceto t s leve will remam outside tank: As the water continues-- In the use of the apparatus, the inlet 4 will accumulate on top of the water and mostly outside of the screen 27 as indicated in Fig. 1. .When it is desired to remove this floating material and clean out the tank'the inlet valve 23 is closed and also the. outlet valve 16; and then the valve 26 is opened to admit water from the main into the outlet Water enters the tank at 22, the oil and substances that did not at once fall to the hot pipe 12. This will cause the inflowing water to enter the tank and force'the contents thereof up through the extension 5 of the tank into the 7 outlet pipe 6, also passing through the sight'tube 7, and ihto the outlet pipe 8. The gasolene and oil floating on top of the water will of course first pass up through the outlets 6 and 7, and will flow through the pipe 8 down into the receptacle 9. By watching the sight tube it can be ascertained when all of the oil and gasolene have been forced upward and out into the receptacle9, and then the valve 26 is closed. Thereupon, the outlet valve 16 is opened .and the air vent valve 20 being open, water will flow out of the pipe 6 and the tank 4 through the outlet 1 1i, until the level is again restored to the line 17 in the tank. Then the valve 34 is opened in the pipe 33 to admit hot water, that will pass through the openings in the coil 30 and .flow down the inner face of screen 27 and serveto melt and remove thick oil or greaseor sediment of any kind-collected in the holes in the screen. It is to be understood that when the tom of the tank, and which float on the sur face had a tendency to collect on the outer face on the screen 27. This hot water will have a tendency to vaporize some of this heavy oil and the vapor andsteam therefrom will pass up through the top outlet pipe 6, and through an extension pipe 35 that is carried upward through the building to the roof -to permit safe escape of such vapors. This hot water flowing into the screen member will tend to fill up the tank, and the outlet valve 16 being opened, it will flow out to maintain the level at 17 in the tank. At this time the siphon inlet valve 20 is closed, to cofipletethe-siphon and with the hot water still flowing in the outlet pipes 13 and 14, will now act as a siphon and qllllickly run ofl' or flush all of the fluid in t e tank. This will permit the inflowing hot water to run down the entire inner face of. the screen 27 and will serve to melt and thoroughly cleanse any accumulation of grease or material of any kind on the screen. At the same time any sediment in the pipe 12 will be softened by the heat and will fiow out through the outlet pipe 14.

-When' the tank has been thoroughly.

7 cleansed, the hot water supply is shut off,

and the valve 10 is closed and the valve again opened, and the tank will perform 1ts norma operation. The airvent pipe 35 is always open so that any fumes from the contents of the tank are carried off to the roof.

Also the pipe 19 is carried upward to the roof to prevent entrance into the building of any vapors from the sewer pipe 14, the water in the pipe 12 preventing their entrance into the tank.

It will be apparent that the operation of the apparatus is very simple, requiring merely the manipulation of certain valves, no extraneous operating means, such as compressed air or pumps is required, and the apparatus is continuous in its operatiouand substantially automatic in its function. The drainage. water flows in continuously from the gara e and other parts of the building, and t e oil and gasolene simply accumulate in the upper portion of the tank. At suitable intervals the accumulation of fluid is removed from the tank in suitable receptacles by simply employing the pressure from the water main and the use of hot water.

It will be seen that the advantages of such an apparatus are twofold. In the first place highly explosive fluids such as gasolene .and the like are absolutely prevented from flowing into the sewers, where the gases accumulate to cause disastrous explosions. .In the second place valuable materials such as gasolene and lubr1cat1ng o1l are saved for future use, instead of being lost by passing into the sewer.
